Dawn was enjoying just feeling him beside her. And when his fingers started to brush her hand, it made her smile a little. At least he was paying attention, instead of still brooding. She knew from past experience that a brooding boyfriend was bad-okay, not her own experience, but from watching Buffy.
When he shifted and lay a hand on her cheek, her eyes shifted to him, then widened a little when he started to lean in-because she knew what he was about to do. When he kissed her, her eyes drifted shut, and she started to return the kiss. Slowly, one of her arms slipped around him, and she began to relax.
